Yep, it is. I got burnt a few times using stop and start in the past.
That is why I only use 'rndc reload'.

Good point. I also got burnt with this one a few times in the past...
now incrementing is my habit. I guess its use depends on the weather.

Not sure what you mean.

This is the only place where I look. As far as I'm concerned, if a
reload was unsuccessful, then you'll get something in there. Otherwise
nothing gets logged.

Not sure about that either. I guess you shouldn't use it then. Anyway,
at least your domain is responding now:
$ host -t a daemonbox.net chadwick.daemonbox.net
Using domain server:
Name: chadwick.daemonbox.net
Address: 66.246.140.170#53
Aliases:
daemonbox.net has address 66.246.140.170
$ host -t a www.daemonbox.net chadwick.daemonbox.net
Using domain server:
Name: chadwick.daemonbox.net
Address: 66.246.140.170#53
Aliases:
www.daemonbox.net has address 66.246.140.170
